There is zero chance that this is supported by the Church in any way.
Catholics are forbidden to take part in such practices, either by conjuring up the dead directly or consulting those who claim to be able to do so.
From the Catechism
******Divination and magic *****
2115 God can reveal the future to his prophets or to other saints. Still, a sound Christian attitude consists in putting oneself confidently into the hands of Providence for whatever concerns the future, and giving up all unhealthy curiosity about it. Improvidence, however, can constitute a lack of responsibility.
2116 All forms of divination are to be rejected: recourse to Satan or demons, conjuring up the dead or other practices falsely supposed to “unveil” the future. Consulting horoscopes, astrology, palm reading, interpretation of omens and lots, the phenomena of clairvoyance, and recourse to mediums all conceal a desire for power over time, history, and, in the last analysis, other human beings, as well as a wish to conciliate hidden powers. They contradict the honor, respect, and loving fear that we owe to God alone.
2117 All practices of magic or sorcery, by which one attempts to tame occult powers, so as to place them at one’s service and have a supernatural power over others - even if this were for the sake of restoring their health - are gravely contrary to the virtue of religion. These practices are even more to be condemned when accompanied by the intention of harming someone, or when they have recourse to the intervention of demons. Wearing charms is also reprehensible. Spiritism often implies divination or magical practices; the Church for her part warns the faithful against it. Recourse to so-called traditional cures does not justify either the invocation of evil powers or the exploitation of another’s credulity. *
What she does is not a gift. It is an exploitation of people who are hurting and desperate after the death of a loved one.
The fact that she claims that the dead approach her of their own volition shows her foolishness. If these spirits are real, then they are not the gentle souls of the dead who wish to communicate with their relatives who are still alive. They are instead demons - satanic spirits - in disguise.
No good can come of it.
